We've learned about the tricuspid valve between the right atrium and ventricle, and the mitral valve between the left atrium and ventricle.
Another valve is called the aortic valve which is between the left ventricle and the aorta.
This valve opens for the heart to pump blood out to all the parts of the body, and then closes so the blood doesn't leak back into the heart.
